My invention relates to improvements in signaling devices and the objectof my invention is to provide eiiicient means by which prearranged,mutually understood, signals may be produced to communicate desiredinformation to persons within the range of Vision of the signalingdevice.

My signaling device is especially well adapted to be installed onmovable conveyances, as motor vehicles or air or water craft, for thepurpose of giving signals required by law, or signals established bycommon usage, relative to the intentions and wishes of the personoperating the vehicle or air or water crait. The signaling device may,however, be adapted for various other uses.

Another object of my invention is to pro vide a signal embodying one ormore arms or semaphores mounted for swinging movement from a neutralinto various signaling positions and arranged to be moved by means thatmay be controlled by an operator located at any desired distance fromthe signal.

A further object is to provide a signal having signal operating meansarranged to be set in motion from a remote point and having stop meansalso controlled from a remote point for predetcrmining the amount ofmovement of the signal operating means to thereby predetermine thesignal that will be given.

Further objects are to provide a signaling device of this nature thatmay be operated and controlled either by electric means, by fluidpressure means, or by hand power means; to provide a signal that isadapted, either for day or night use, the same being equipped with lampsby which it may be illuminated at night, to provide a signal having atransparent or light conductive housing that is equipped withautomatically operated wiper means by which it will be kept clean andtree from dirt and moisture so that it will be readily visible under allweather conditions.

it still iurther object is to provide a signal of this nature which maybe equipped with two or more signal arms movable to various diil'erentsignaling positions to thereby pro- 1927. Serial No. 201,802.

It will be noted that all of the modifications shown in the figureshereinbefore described embody one or more swingingly mounted signal armsarranged to operate in the same manner, the mechanism for moving thesignal arms being different in the different modifications.

Like reference numerals designate like parts throughout the severalviews.

Referring first to Figs. 1 to 10 inclusive, the numeral 1 designates ahousing adapted to be secured to a fixed support, as to the frame, or toany fixed part, of a motor vehicle, and 2 designates,in a general way, asignaling member or semaphore, hereinafter termed a signal arm, that isarranged at right angles to the housing 1 and rotatably connected withwhat I shall hereinafter term the forward end of said housing 1.

3 is a normally horizontal, tubular shaft that is supported for rotationin suitable bearings 4, 5 and 6 in the housing 1 and projects outwardlyfrom the forward-end of said housing. A rear frame member 7 of thesignal arm 2 is provided with a hub 8 that fits over the end of thetubular shaft 3 and is secured thereto by pins 9 so that when thetubular shaft 3 is rotated the signal arm will be caused to swing intovarious signaling positions. A fitting or sleeve 10 is screwed over theend of the hub 8 as shown in Fig. 2 and is provided, on its end adjacentthe housing 1 with an annular extension 11 that fits rotatably within asuitable groove the end a of the housing 1 thereby forming a neat andweatherproof connection at this location. A sleeve 12 to the rear of thebearing member 5 prevents the tubular shaft 3 from moving forwardlongitudinally. A relatively fixed, non-rotatable shaft 13 extendslongitudinally within the tubular shaft 3 and projects from the forwardend thereof. A disc member 14: is fixedly secured to the forward end ofthe shaft 13 within the signal arm 2 and is provided on its front andrear sides with mutilated or segmental gears 14 for purposes hereinafterexplained.

A signal arm housing 15 is secured to the rear signal arm frame member7, and a relatively long transparent front lamp casing 16 is secured tothe signal arm housing 15, said lamp casing 16 being arcuate in crosssectional shape.

17 is a cylinder within the housing 1, and 18 is a piston reciprocablewithin the cylinder 17 and having a piston rod 19 that extends outwardlythrough a suitable gland in the front end of the cylinder and is securedto a yoke 20. The yoke 20 is guided for movement on the shaft 3 and ontwo guide rods 21 and said yoke 20 is provided with a finger or pawl 22that fits within a spiral groove 23 in the shaft 3 and serves to rotatesaid shaft 3 as the yoke 20 is moved lengthwise within the housing 1,thereby rotating or swinging the signal arm into various angularsignaling positions. Compression springs 20 on the shaft 3 abut againstopposite sides of the yoke '20 and always serve to return said yoke tothe initial or inoperative position after a signal has been given. Thepitch of the spiral groove 23 is preferably of'such a degree as to causethe signal arm 2 to be moved through substantially one half of onecomplete turn, (180 degrees), when the piston'18 is moved from itsinitial mid way position, shown in Fig. 1, completely to either end ofthe cylinder. To limit the movement of the signal arm 2 to less than 180degrees, stop means are provided for arresting the movement of the yoke20 at a plurality of different points as desired. These stop means areillustrated as being in the form of electromagnets or solenoids 24,having plungers 25 adapted to extend upwardly in alignment with notches26 in the yoke 20, one series of solenoids being provided on each sideof the central or neutral position in which the yoke 20 is shown inFig. 1. The electromagnets may be mounted on a base of insulatingmaterial that is secured within the bottom of housing 1. The plunger 25of each electromagnet 24 has one end of a downwardly curved spring 27secured to its upper extremity, the other end of each spring 27 beingsecured to a suitable support or bracket. The springs 27 of the seriesof electromagnets to one side of the central position of the yoke 20 areinclined in one direction while the springs 27 of the other series ofelectromagnets are inclined in the opposite direction. All of theplungers normally remain in the raised position ready to intercept theyoke 20 and arrest the movement of the same. One series ofelectromagnets is arranged to prevent movementof the yoke 20 in onedirection while the other series of electromagnets is arranged toprevent movement of the yoke 20 in the opposite direction. The yoke 20is arranged to ride over either series of inclined springs 26 anddepress the plungers connected therewith as it returns toward theneutral or initial position. Suitable electric circuit and switchcontrol means are provided for energizing any one or more of theelectromagnets 2 1 to retract the plungers 25 connected therewith andpermit unobstructed movement of the yoke 20 past said plunger ashereinafter described in connection with Fig. 8.

The cylinder 17 has fluid conduit pipes 28 lit;

and 29 as shown in Fig. 8 respectively connected with opposite endsthereof through which fluid under pressure, as compressed air, may enteror exhaust from the cylinder. The pipes 28 and 29 connect with a valvehousing 30 that has a slide valve 31 therein. The slide valve 31 isarranged to be moved in opposite directions by two electromagnets 32 and33 respectively that are connected with opposite ends of the same.Springs 34 exert a pressure against armatures 35 and return the slidevalve 31 to the neutral position shown in Fig. 8 when neither of theelectromagnets 32 or 33 is energized.

A fluid pressure tank 36 is connected with the valve housing 30 at twospaced points by branched pipes 37 and 38. T ie slide valve 31 isprovided with two spaced, diametrically arranged conduits 39 and 40 andis further provided with two spaced cavities 41 and 42 as shown in Fig.8. lVhen the slide valve 31 is in the mid position shown in Fi 8 thecavities 41 and 42 will connect the respective pipes 28 and 29 withconduits 43 that open to the atmosphere leaving the cylinder 17 fullyexhausted of all positive or negative fiuid pressure. It electromagnet32 is energized slide valve 31 will be moved to the right Fig. 8,causing diametrical conduit 40 to register with pipes 37 and 29,admitting iiuid under pressure to one end of cylinder 17 for moving thepiston 18 in one direction. At the same time the cavity 41 will connectthe pipe 28 with an air outlet or exhaust pipe 44 relieving pressurethat might otherwise be built up on the opposite side of the piston 18.In a similar manner, it electromagnet 33 is energized slide valve 31will be moved to the left bringing passageway 39 into registration withconduits 38 and 28 and connecting conduit 29 with one of the exhaustpipes 44.

Electromagnets 32 and .33 each have one terminal connected by circuitwire 45 with one side of a battery 46, the other terminal of 32 beingconnected by circuit wire with each individual switch of a group ofswitches 48, while the other terminal of 33 is connected by circuit wire49 with each individual switch ot a group of switches 50. When anyswitch of the group 48 is closed the electromagnet 32 will be energizedand when any switch of the group 50 is closed the electromagnet 33 willbe energized.

The group of switches 48 is also used for controlling one series 01. theelectromagnets 24 that govern the stopping and limit the movement of theyoke 20 in one direction while the group of switches 50 is similarlyused for controlling the other series of electromagnets 24 that governand limit the movement of the yoke 20 in the opposite direction. Eachswitch of both of the groups 48 and 50 has one terminal connected bycommon circuit wire 51 with the battery 46 and the other terminal orterminals connected by separate circuit wires 52 with one or more of theelectromagnets 24. In Figs. 9 and 10 I have shown one form of a switchthat may be used for this purpose, said switch being of the push buttontype and having one terminal 53 to which the common circuit wire 51 maybe'connected and a plurality of terminals 54 for connection with one ormore of the separate circuit wires to the electromagnets 24. In practiceone of the switches of each group will be connected with the firstelectromagnet 24 adjacent the yoke 20, the next switch of the group willbe connected with the first two electromagnets 24, the third switch willbe connected with the first three electromagnets and the fourth switchwill be connected with all four electromagnets 24 of the group on oneside of the position of rest of the yoke 20. hen the connections aremade in this man her the closing of the first switch of either groupwill retract the first plunger 25 and permit movement of the signal armto the first signaling position while the closing of the second switchwill retract the first two plungers 25, the closing of the third switchwill retract the first three plungers and the closing of the fourthswitch will retract all four plungers. More switches and more plungersmay be provided if a greater number of signaling positions are desired.It will be apparent from the preceding description that the closing ofany switch in either group 48 or 50 will simultaneously energize eitherelectromagnet 32 or electromagnet 33 and the desired ones of theelectromagnets 24. Thereby setting the stops for the yoke 20 and atthesame time admitting the compressed fiuid for moving said yoke inthedesired direction.

The signal arm 2 is provided, in substantial alignment with the shaft 3,with a larger signal lamp 55 disposed in a curved reflector housing 56and connected by suitable wires 57 with a switch contact ring 58 on themovable frame member 7. Another contact 59, preferably spring pressed,is provided on the fixed end 4 of the housing 1 and is connected withsuitable circuit wires by which current may be supplied for illuminatingthe lamp. If desired the contact ring 58 may be interrupted at thelowermost point, corresponding to its position of engagement with thefixed contact 59, when at rest, so that the lamp or lamps will not belighted when the signal arm is in the position of rest but will belighted the instant the signal arm is moved in either direction toward asignaling position. A plurality of smaller lamps 60 may be provided inthe transparent signal arm casing 16 below the larger lamp 55 andconnected with the same circuit wires 57 Two wiper members 61 and (52each having squeegee strips 63 are adapted to be moved over the arcuatetransparent front 16 of the signal arm to keep the same clean and insuremaximum visibility under all weather conditions. The wiper members 61and 62 have arms 64 on their ends, arranged at right angles thereto, oneset of said arms being connected with tubular shaft 65, which, in turn,are connected through gear trains 66 with shafts 67 and 68 that areprovided with bevel gears 69 on one side of the disc 14. The other setof wiper arms 64: are connected with shafts 70 that extend through thetubular shafts and are connected by gear trains 71 with shafts 72 and 73having bevel gears 7% that mesh with the multilated gears 14' on thediscl l. The tubular shafts 65 are journaled in the ends 15 of thesignal arm frame and the shafts are journaled in the shafts 65. Therespective gear trains 66 and 71 are shown in Figs. 4 and 5. When thesignal arm is moved away from the neutral position the bevel gears 69and 74 are caused to move around the stationary disc ll and will berotated by reason of their meshing with mutilated gear segments 14'thereby transmitting rotary movement through the interconnecting shaftsand gear trains to the wiper members 61 and 62 which wiper members willbe caused to move around the transparent shell 16 toward each other. Thegear ratios are preferably such as to cause the wipers'to make theirfull travel while the signal arm is being moved to the first signalingposition, the bevel gears running off of the mutilated gears at thispoint and no further movement of the wipers taking place until thesignal arm is returned toward neutral whereupon the bevel gears willagain engage the relatively fixed mutilated gears and the wipers will bereturned to their initial less radius are smaller than the other twobevel gears to equalize the gear ratio at the two ends and prevent anytendency toward moving one end of the swipe members faster than theother.

In the operation of this device when any switch of the group 48 isclosed the signal arm will be caused to swing upwardly in one directionthrough a predetermined angle and when any switch of the group 50 isclosed the signal arm will be caused to swing upwardly in the oppositedirection through a predetermined angle. In this way any desired signalmay be given.

In Figs. 11,12 and 13 I show amodilied form of the invention in whichtwo signal arms 75 and 76 are provided, said signal arms being adaptedto hang vertically when no signal is being given and to be swung inopposite directions in giving a signal. The arms 7 5 and 76 areindependently movable to different signaling positions and make possiblethe display of a large number of different signals that can not be shownor displayed by the use of a single arm, it being obvious many differentsignals may be formed by varying the relative positions of the two arms.

The signal arms 75 and 76 are similar to the previously described signalarm 2 and may, if desired, be provided with similar wipers although saidWipers are not herein shown or described. A single large lamp 77 commonto the two arms 75 and 76 is provided at the top and a plurality ofsmaller lamps 78 are distributing longitudinally along said arms.Suitable electric-contact means 79 of a general form similar to thathereinbefore described is provided for transmitting electric current tothe lamps 7 7 and 78. The signal arms 75 and 76 have hubs 80 and 81respectively formed at their upper ends, the hub 80 being secured to ashaft 82 and the hub 81 being secured to a sleeve 83 that is rotatableon the shaft 82. The shaft 82 and sleeve 83 are both rotatably mountedin suitable bearings 84 in the upper portion of a housing 85 thatarranged parallel with the signal arms, 7 5 and 76 and contains themeans for operating said signal arms. In this form of signaling devicethe operating means disclosed in the drawings comprises two flangedgearwheels 86 and 87 secured to the shaft 82 and sleeve 83 respectivelyand engaged respectively by gear racks 88 and 89. The gear racks 88 and89 are positioned on opposite sides of their respective gearwheels 86and 87 for rotating the shaft 82 and the sleeve 88 oppositely to swingthe signal arms upward in opposite directions, and said gear racks arerespectively connected with pistons 90 and 91 in cylinders 92 and 93.Fluid under pressure is admitted to and exhausted from the cylinders 92and 93 through conduit pipes 94 that are connected withelectromagnetically operated valves 95 which may be controlled in asimilar manner to the valve 30 shown in Fig. 8. The wiring and switchmechanism used in connection with this form of the invention is notshown in detail. The rack bars 88 and 89 each have a ratchet lug 96provided thereon that is adapted to be engaged by a plurality of stopplungers 97 arranged in the path of movement of said lug to predeterminethe position or the amount of movement of the rack bar. The plungers areslidable within electromagnets 98, one electromagnet being provided foreach plunger, the electromagnets being adapted, when energized, toretract the plungers and the plungers being normally held outwardly inthe path of the lug 96 by springs 99. The plungers 97 act as positivestops to limit the upward movement of the rack bars 88 and 89, exceptwhen they are retracted by the electromagnets 98, but the ends of saidplungers are inclined on their upper sides as at 100 so that theinclined lower sides 101 of the ratchet lugs 96 will ride over andretract the plungers as the rack bars move downwardly. The operation ofthe signal shown in Figs. 11, 12 and 13 is similar to the operation ofthe previous ly described signal except that both signal arms may beused in giving a signal instead of only one, thus making possible thegiving of a greater number of signals.

In Figs. 14, 15 and 16 I show a modified form of signal and operatingmechanism therefor which conforms substantially with the signal shown inFigs. 11, 12 and 13 except that this device is entirely electricallyoperated. In said Fig. 14, I show a housing 102 having two signal arms103 and 104 connected therewith for swinging movement in oppositedirections in the same manner as shown in Fig. 12, said arms beingsecured to a shaft 105 and a sleeve 106 respectively that have gearwheels 107, only one of which is shown secured thereon. Said gearwheels107 are raclr bars 108 having pawls 109 arranged to be engaged by stopplungers 110 operated by electromagnets 111. The rack bars 108 extenddownwardly into double electroi'nagnets or solenoids 112113 and areconnected with cores 114 that are adapted to be moved by theelectromagnets 112113 to transmit movement through the rack bars 108,gearwheels 107, and shaft 105 or sleeve 106, to one or both of thesignal arms 103-104. In each electromagnet there are upper and lowerbuffer springs 115 to cushion what otherwise might be a shock at the endof travel of the core 114. In this form of device I show three of thepositioning electromagnets 111 in connection with each rack bar andprovide positive lined stops 116, only one of which is shown to limitthe upward movement of the rack bars. The wiring and electricalconmotions to the various electromagnets shown in Fig. 14 is not hereindescribed in detail but may be made in substantially the manner shown insaid Fig. 14. In the diagram a portion of the wiring is omitted. Theswitches for controlling the circuits to the electromagnets 112113 maybe of the form shown in Figs. 15 and 16 so that the current may beconveniently switched from one to the other of said electromagnets toreverse the direction of movement of the core 114 or to return said coreto the inoperative position. This switch comprises a housing 140 havingan arcuate receptacle 141 in the bottom of which is embedded a commonterminal or contact 142 and two sets of contacts 143 and 144. Anoscillating contact member 145, pivoted at 146 and having finger piece147 is provided with an insert of conductive material 148, adapted tobridge the common terminal 142 and either one of the sets of contacts143 or 144 when said contact member moved to either side of the centralposition. A spring 149 normally holds the contact member 145 in theinoperative position shown in Fig. 15.

In Figs. 17 to 21 inclusive I have shown a 123 respectively that arerotatably mounted on a tubular bearing member 124 which is supported bya frame plate 125. The hubs 122 and 123 are each provided with grooves126 around which, operating cables 127 and 128 respectively are looped.The operating cables 127 and 128 pass outwardly between the signal armsand 121, preferably to the rear, over guide sheaves 129 that are supported from the frame bracket and said operating cables are conducted toa remote point and there connected with the bottom ends of operatinglevers 130 and 131 that are movable between guides 132. The upper endsof operating levers 130 and 131 are connected with stub shafts 133, Fig.21, on hand levers 134. The stub shafts 133 are pivotally mounted infixed plates 135 and the hand levers 134 are provided with springpressed detent members 136 movable over notched segments 137.

Movement of either hand lever 134 will move the operating lever that isconnected therewith, causing it to transmit movement through the cable127 or 128 to the signal arm 120 or 121 that is connected therewith. Inthis way the signal arms 120 and 121 are moved into various signalingpositions. The signal device of Figs. 17 to 21 has a relatively largeaxially arranged signal lamp 138 and the arms 120 and 121 are eachprovided with a plurality of smaller lamps 139, Fig. 19, contact meanssimilar to that hereinbefore described is provided in connection withthis form of the device as shown .111 Fig. 15 for supplying electriccurrent to the lamps.

In all of the modifications hereinbefore de-. scribed the same principleof operation is maintained, the signaling being accomplished by one ormore swinging arms arranged to be held in different positions to givedifferent signals.

If desired, the two arms of any of the double arm signals may be securedtogether and operated as a single arm. The lights in the several signalsmay be varied as to color, number, size, and arrangement as desired.
